Bimetallic thermometerIt is an on-site detection instrument for measuring low and medium temperatures, which can directly measure the temperature of liquid vapor and gas media within the range of -80 ℃ to 500 ℃ in various production processes. Its main component is a multi-layer metal sheet composed of two or more metal sheets stacked together, which works based on the principle that two different metals expand differently when the temperature changes. It is composed of bimetallic sheets wound into a circular bending shape. When one end expands due to heat, it drives the pointer to rotate, and the working instrument displays the temperature value corresponding to the thermoelectric potential.
Temperature gauge form:
1. Hot sleeve type: The universal surge type bimetallic thermometer is particularly suitable for use in high-temperature, high-pressure, or volatile hazardous gas decomposition environments. If the instrument is damaged and needs to be replaced, it must be cooled, depressurized, or shut down. By using a hot set bimetallic thermometer, when the instrument is damaged and needs to be replaced, there is no need to cool down, reduce pressure, or stop the machine. Only the instrument core needs to be replaced, and the enterprise can achieve continuous production.
2. Angle type (axial type) refers to the form in which the axis of the detection element is perpendicular to the plane of the dial, also known as axial type.
3. The form in which the axis of the straight (radial) detection element is parallel to the plane of the dial, also known as the radial type.
4. Universal type: In addition to having the function of angular straight type, it can also be converted from angular type to straight type or from straight type to angular type, and can be infinitely adjusted by the user. The material of the corrugated pipe and structural components used is 1cr18Hi9Ti stainless steel, making it easy to use and corrosion-resistant.
Note:
① Thermometers are generally manufactured in angular form, meaning that the zero position does not need to be adjusted when used in angular form. If the user needs a straight type factory, it must be specified when ordering.
② When the thermometer is converted from a straight type to an angle type or from an angle type to a straight type, there may be slight changes in the thermometer reading, which can generally be ignored. If the user has higher requirements, they can adjust the zero position when changing the type themselves. The user can unscrew the watch cover counterclockwise, then use a wrench to loosen the dial lock nut counterclockwise and adjust the "0" position in the water point slot. Finally, tighten the nut and watch cover.
